With production underway for Season 6 of HBO’s “Game of Thrones,” new cast will be joining the ensemble cast and EW reports that actor Ian McShane will be returning to HBO following his Golden Globe-winning role on the Western “Deadwood” to play an undisclosed role.

The original story says that McShane “has a relatively small amount of screen-time during the season, yet his character is of key importance.”

The ten episodes currently under production will air on HBO in the spring of 2016.
